Calculation: (2x ^ 2) ^ 2 + (- 3x) ^ 3 · (- 2x)
The beauty of Mathematics
(2x²)² + (-3x)³·(-2x)
= 4x⁴ + (-27x³)·(-2x)
= 4x⁴ + 54x⁴
= 58x⁴
The result of calculating 2x ^ 2 * (- 3x ^ 3) is
2x²*(-3x³)
=[2×(-3)]x^(2+3)
=-6x^5

2X + {3x (12.5-x)} = 30, right? How to calculate?
2x+{3X(12.5-x)}=30
2x+{37.5-3x}=30
37.5-x=30
x=7.5

Infinitesimal in limit problems of higher numbers In the limit of higher numbers, the definition of infinitesimal is f (x) when x approaches to x0 or when the limit is zero, then f (x) is called the infinitesimal of X in this process. However, in the related proof later, it seems that the definition of infinitesimal when x approaches to x0 appears again. By definition, isn't infinitesimal only a function? Why can it be replaced by a specific symbol (constant?)? Thank you~
